description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to collapsible lunch boxes. I i

One of the principal objects of the invention is to provide a durablepaper lunch box which can be quickly expanded for use in carryingalunchand which can be immediately folded into a flat condition to becarried in the pocket.

Another object of the invention is to provide a paper lunch box whichcan be expanded to contain a lunch and which will be provided with apaper handle extending around the box to form a brace, said handle beingformed of a strip of paper which serves as a latch for holding the coverclosed and which also serves to hold the box in collapsed or flatcondition for carrying in the pocket.

These and other objects may be attained by means of the constructionillustrated in the accompanying drawings, in which,

A Figure 1 is a perspective view of a paper lunch box made in accordancewith this invention and showing the cover opened and thrown back, Fig. 2is a perspective view of the paperlunch box closed, Fig. 3 is a centralvertical sectional view of the same, Fig. 4 is atransverse sectionalview of the box when folded flat, and Fig. 5 is a plan view of the blankfrom which the box is formed.

Referring to the drawings, the numeral 1 designatesvthe bottom of thebox, 2 are the ends, 3 is the front side, 4: is the back, and 5 is thecover. The ends2 are provided with flanges 6, and when the front and theback A are bent upward upon the lines a the flanges 6 are bent at rightangles to the ends 2 and secured upon the outer-sides of the front andback, as shown more clearly in Fig. 1. The cover 5 which is formedintegral with the body portion of the box is also provided with a downturned flange 7 which overlaps the frontedge of the box when closed.

A paper strap 8 is secured to the top or cover 5 by means of fasteners 9to form the handle. 10. A ball and socket fastener is utilized forholding the cover closed when the box is expanded and also for holdingthe'box in a collapsed or folded position when empty. The ball member 11of the fastener is secured to the front of the box and the end of thestrap 8 is provided with a socket 12 to receive the ball member and thushold the box in closed position when expanded.

When the box is empty and in condition to be folded flat, the bottom 1is folded on the central line b, as shown in Fig. 1, and the ends 2 arefolded on a central vertical line 0. The bottom 1 is also folded on theconverging lines d and when the parts are brought together the strap 8extends around the box and the end of the strap engages the ball member11, said strap having a socket member connected thereto [at the properpoint to hold the box folded flat.

From the foregoing, it will be obvious that a folding lunch box made inaccordance with this invention may be formed of paper or leather whichwill carry a sufficient lunch and when the lunch has been removed, thebox can be folded and placed in the pocket to be used the next day. Thebox is durable in construction, is braced by the handle strap and whenfolded occupies but little space in the pocket. The lunch box can be cutfrom a piece of paper without material waste and can be produced at lowcost.

Various changes may be made in the details of construction withoutdeparting from the spirit and scope of the invention as defined in theclaim.

What is claimed is A collapsible lunch box made from a single piece offlexible material and comprising a bottom, a front and back, ends havingangular flanges secured to the front and PatentedSept. 22, 1914.
